Discoloration time and fading time for color-changing lenses

In general, color-changing lenses take about 30 seconds to 1 minute to darken on average when exposed to sunlight/UV and will continue to darken for about 10 minutes to reach the lens depth of full-color sunglasses. Color-changing lenses of good quality and workmanship are restored to an almost clear and transparent state in 2 minutes and completely cleared in 5 minutes, although the high temperature can affect this. If you want to change a single color change lens, the color of the old and new lenses will be inconsistent. This is because the discoloration performance of the old lens will be reduced due to the long-term use of the discoloration agent. Therefore, in order to ensure the normal use and aesthetic appearance, it is usually recommended to replace the two lenses at the same time.


Glasses Size - Frame Width

To really know how big a frame is, and how it will look on your face, you have to determine the width of the entire frame. The outer width of the frame is the distance between the visible areas on the left and right sides of the frame, namely, the distance between the frame and the junction of the two temples. The inner width of the frame is the distance between the inner sides of the two temples at 60mm behind the plane of the lens. This is just the contact point between the temple and the human temple. If it is too tight or too loose, it will affect the wearing comfort. The weight of the frame is evenly distributed across the bridge of the nose (or evenly distributed between the two nose pads on the bridge of the nose).



Frame Selection of Progressive Sunglasses

Choose a proper frame range. Only if the frame is not very large and beveled, the frame can be very flat. Because the distance from the glazed to the optical center of a progressive multi-focus lens is 19-17 mm, and the distance between the edges of the frame will be no less than 28 mm if the area inside the lens can be used at close range while maintaining the far sighting field.

What Are Pinhole Glasses?

Pinhole glasses, also called stenopeic glasses, are plastic eyewear with hundreds of pinhole-sized perforations in place of lenses. Pinhole glasses are mostly used to improve refractive errors in the eye because they shield the eye from indirect rays of light which can distort vision. This would decrease the blur circle on the back of the retina.


The History of Clubmaster Glasses

Clubmaster glasses are a variation of the browline sunglasses made popular in the 1950s. The lenses of clubmaster glasses are typically held in place by a thin metal frame and are of a squared-off round shape.

Although many people believe that the Cubmaster glasses root back to the 1950s, the fact is that clubmaster glasses or clubmaster sunglasses as we know them didn’t come about until Bruce Willis wore a pair of Shuron Ronsirs browline glasses with tinted lenses on the TV series Moonlighting in the mid-1980s.

From that moment, browline glasses draw the public’s attention. By the 1960s, Ray-ban was a fairly large contender in the market and its owner Bausch & Lomb was one of the top manufacturers of browline-style eyeglasses. And then the Ray-ban launched the first browline sunglasses, called it clubmaster. Sales were enormous almost immediately and despite only coming out mid-80s, they still ranked as the third most popular style of sunglasses sold in the decade, next to Ray-bans Wayfarers and Aviators.

Then Ray-ban took every revision of the original 1947 Browline and began offering it as part of the clubmaster series. From bold brows to lightweight metal caps first introduced in the 1950s, the clubmaster offered a style that could fit elegantly on just about any face shape. After that, the clubmaster glasses have been popular for a long time.
